Ed Norton has revealed he's open to the idea of making another film with his Fight Club co-star Brad Pitt.
The actor, who appeared alongside Brad in the 1999 David Fincher action movie, said he wouldn't rule out a reunion on screen but warned it would be tough to organise.
"It's a possibility," he told the Independent. "We've talked about it but me and Brad being in something together is a complicated thing to put together."
Ed plays a convicted arsonist in new film Stone, which also stars Robert de Niro and Milla Jovovich.
But the actor - who was appointed a UN Goodwill Ambassador for biodiversity last year - says he's not fussed about getting plenty of screen time.
"I try not to work when I don't feel it," he explained.
"I don't have anything to prove to anybody, which is a lovely place to be."
